VERIFICATION OF NC TOOL PATH AND MANUAL AND AUTOMATIC EDITING OF NC CODE

Abstract

We describe the method of verification and manual and automatic editing of the NC code. A new method was proposed to find out the errors quickly and to edit the errors easily. Both wireframe display of tool path and solid display of machined part are used to detect the motion command errors and auxiliary command errors in NC code. The Z-map method was used for the shaded image display and the comparing the CAD data and CAM data. Using the verification result, the NC program was edited manually without returning to the programming stage. In addition, an automatic editing was proposed to overcome the limit of manual editing. The method was implemented as a software in an IBM/PC with the MS-Windows.
